## Key figures and their sources

| Metric | Value | Baseline | Detail | Source |
| --- | --- | --- | --- | --- |
| Higher inference throughput | +29–40% | vs. a single local NVMe drive | Qwen3-Coder-480B-FP8 in TP=8 production topology under a long-context cold-recovery load: +29% at concurrency 8 and +40% at concurrency 16, the operating point with the largest gain; +35–36% for the whole machine in the dual-instance TP4×2 layout. | Measured · [R2](https://vuke.top/en/evidence/R2) [R3](https://vuke.top/en/evidence/R3) |
| Lower time to first token (TTFT) | −26–32% | vs. a single local NVMe drive | Across three concurrency levels of the same 480B TP8 load, TTFT p50 falls from 10.17–35.73 s to 7.53–26.35 s. | Measured · [R2](https://vuke.top/en/evidence/R2) |
| Faster than recomputing without external storage | 8.6–20× | vs. full recompute with no external storage | At concurrency 16, TTFT p50 is 149.5 s when recomputing and 11.85 s with FX100; throughput is 4.1 tok/s versus 74.9 tok/s. | Measured · [R2](https://vuke.top/en/evidence/R2) |
| TTFT gain from the LMCache parallel-read patch | 4.1× | vs. before the patch | One GPU, concurrency 16, cold read from disk (Qwen2.5-32B): TTFT 37.97 s → 9.30 s; read bandwidth 0.98 → 5.23 GB/s, about 5.3×. | Measured · [R1](https://vuke.top/en/evidence/R1) |
| Faster model loading | 6.2–9.3× | vs. NFS, on Huawei Ascend 910B | On Huawei Atlas 910B: DeepSeek-32B serving load 691 s → 112 s (6.2×); DeepSeek-70B 1399 s → 150 s (9.3×). | Measured · [R9](https://vuke.top/en/evidence/R9) |
| Faster training checkpoint saves | 1.9× | vs. the baseline in report R1 | 8-GPU 32B LoRA with 65.6 GB full-model snapshots: 178 s → 94 s; sustained write bandwidth 3.26 → 6.40 GB/s (+96%). | Measured · [R1](https://vuke.top/en/evidence/R1) |
| Effective compute utilization under model switching | 46.7% → 62.8% | at 20 model switches per hour | Modeled from measured load times: at 20 model switches per hour, effective compute utilization rises from 46.7% to 62.8%. | Measured · [R1](https://vuke.top/en/evidence/R1) |
| Concurrent model loading on 8 GPUs | 16% / 30% | vs. the baseline in report R1 | Eight GPUs cold-reading models at once: 16% faster wall-clock overall and 30% faster per model. | Measured · [R1](https://vuke.top/en/evidence/R1) |
| Deviation between two independent runs | ≤5% | same load level, measured twice | Two independent runs at the same load level deviate by no more than 5%; cross-instance hot sharing through the fs:// shared pool was verified in the same campaign. | Measured · [R3](https://vuke.top/en/evidence/R3) |
| HBM residency an external KV tier can stand in for | 128 GB | MetaX N260 single GPU, 14B model, seven-way comparison | Conclusion of a seven-way comparison on a 14B model: an external KV tier can stand in for 128 GB-class HBM residency. That campaign ran on a single MetaX N260 GPU; the method carries across platforms, the numbers are not mixed with MI308X results. | Measured · [R5](https://vuke.top/en/evidence/R5) |
| ComfyUI + LTX-Video 2.3 models running end to end | 7 / 7 | AMD MI308X, ROCm 7.2 | All 7 delivered models (3 VAEs, the fp8 text encoder, the text projection and 2 LoRAs) run end to end on MI308X / ROCm 7.2 with no dtype, operator or kernel errors. | Measured · [R6](https://vuke.top/en/evidence/R6) [R7](https://vuke.top/en/evidence/R7) |
| Arrays to inference nodes | 1 : 8 | production sizing basis | One FX100 serves 8 inference nodes; 100 GbE sustaining KV read-back for 8 nodes is a measured anchor. On the joint-test basis, storage spend stays within roughly 10% of the GPU budget. | Estimated · [R1](https://vuke.top/en/evidence/R1) [R2](https://vuke.top/en/evidence/R2) [R3](https://vuke.top/en/evidence/R3) |

A note on names: in earlier test-report filenames FX100 appears as AISSD5000, and before that as WS5000 / GP5000; some reports are signed “Mingxin”. They all refer to the same product. This site uses the FX naming throughout (FX100 / FX200 / FX300 / FX400), while report entries keep their original titles so you can cross-check.
